the slide mounted in the carrier and adapted to slide therein for thepurpose of conveying the mold from casting; to ejecting` position.v

The mold proper consists of tour members, viz: the lower jaw or' body l;the upper jew or cap 9.; and the two springinipelled, spring-yielding,side pieces 3 and 5 housed, the one,3,in the lower ian',:ind the other,5, in the upper jew, and termin the side walls ofthe slot. They :irespring pressed, by springs i. and (3, each toward the fece ot the y'opposite jaw, forming' tight fitting side wells which areself-adjusting to variations mdis tance betweenthe upper and lower jaws.rlhe upper `inw is capable of vertical movement to and from the lowerjaw in orderto vary the width o'l the slot, and pressed upward by thesido pieces 3, 5, which tend to open the mold, it moves up and down inguides 1G in the slide-there being a tongue and grooveyor equivalent.,connection tween the slide and the inw, whereby the letter, as it movesup and down, is held in its proper relation to the lower jaw. T he lower'uw l is seated in al ugreove in the lower portion of slide l and isheld in place .between the back of the slide and the trent plate S,which term a guideway wherein the jaw can more lengthwise. This movementof the lower jaw will, according lo itsdireo tion7 cause the side piece2% which it. carries te apln'oach or recede irom the other side piece 5,thns varying the length of the slot as desired. '.lhe slide lr held and`guided in its movements in the carrier G, by :i longitudinal rib 30 onits top', which enters a corresponding groove inthe carrier; and by arib 2L). on its bottom, which enters a. cor'- respondingguido slot orgroove in the carrier. The slide may be moved at propel' intoi-vals,from casting to eje'cting` position 'and return, by'any suitablemeans-tyliilied in the drawing (Fig. l) bythe connected by link 5l tothe slide, said pitman rod being actuated by any proper means. ln lieuof this arrangement for actuatingl the slide l :an use the rack andpinion arrangement illustrated in my aforesaid application Serial No.308,522. rlhe parts aS thus far described are substantially similar ingeneral construction and operation to the pnrtsidentitied by likereference characters in my application Serial No. 303,522.

l come now to th ose portions of the mechfm'ism wliich'ennbody myimprovements..

The side piece 3, which Jorms the lei-l.

.bearing upwardly hand side wall of the mold Islot' in Fig. l. isprolonged in the form of a lengthwise extendiug'sirijp oi' bar c solidwith the piece l andthe other end of this bar a is supported andupwardly pressed by a second spring l,

similar in construction.` arrangement and function to the spring ilwhich supports and upwardly presses the side piece tl. This liar of thejaw a is so arranged and formed that when the length of the slot isdecreased by moving the lower jaw l. and consequently the side piece theuinised portion of of the melting pol, he exposed. '"llie bar f/ isvertically slotted lower I ,serving as a guido tosteady and hold the.spout 'closing barfor prolongation a, in propel' position during its upalid down movements. ',lhe upperjaw also has a tail or prolongation "cwhich extends through/a the left hand guide slot orv opening Ai istandard I6 in the slide F, and .bears upon the upper face of the bar uwhen the parts are-iii the'position sliownin Figxll. In this way theside piece/3 gets a broatLeXtended against the upper-sjaw. *whichlpermits it the side piece) to be -niorcd to contract the length ot' 'themold space oi"3slotfwitliout any danger of the ofthe upper jaw whichpoint between the two. To adjlls't 'the u per jaw for the purpose ofvaryingthewit th of the slot, I make use preferably on the jaw, and thelatter on the slide in whlch the jaw is'mounted. And with thisniechanlsin I combine means by which the pinion carrying shaft, beforethe ejceting the drawing in the of the cast slug, is automaticallyrot-ated iii afdirection and far enough to relieve the pressure of theupper jaw upon the slug; .and also-means by which the shaft isautoniafticallyA returned to-its original position a er the operation ofejecting lthe cast slug a d beforel the o eration ofcasting anothers-ie'. Devices fdr. these purposes ca n be widely varied. They ai'erepresented in form in which I now prefer to .employ them.

Upon the back of the upper jaw, are

"-fornied or'attached two vertical toothett racks d, and meshing withthese racks are two pinions e, is niountcdvto revolve in bearings g onthe slide, and is provided at one end with any suitable' operating1neans-for example the handle L-as shown more clearly in Figs. 1, 2, 6.-By turning the. handle to'rotate the shaft in one d' ection or theother, it will be' seen that t e upper jaw can be raised t lowered soasjto be placed at the desired tance from /the lower jaw. The upper Jawof a rack andpinion inechanism--tlie former.

In Figs. (3 and 7 is shown one means of automatically eti'ecting theslight .lift-ing of the upper jaw I leferrnig to these figures, n is astud or projection with rounded end, extendingrearwardly from the outerend of arm and o is an incline secured to the ejeeting end of the-oarrier fi'aine G in such position that j ust before the slide F in itstravel from casting position reaches ejecting position the stud n. willmeet the incline o and by the continued movement of the slide F will becaused to travel over the inclined surface of o with the resultofforcibly turning the arm 7n, and consequently the shaft f, against thestress of spring l, in a direction to lift the upper jaw, so that by thetime the slide reaches ejecting position, the mold will have beenautomatically opened to the desired extent. j. 1 l A j ln Fig. 7 thestud 4is represented in dotted lines in thel position it occupies whenthe parts are in ejecting .position-liaving travei-sed the incline. alidresting against a Hat surface beyond' the incline where it is held vsolong as A s soon', however, asthe mold. on its returni the mold is inejecting position.

to casting position'lnoves far Venough to disengage the stud from theincline, the mold will automatically close and the parts will resumenormal position. Iii lieu of this mechanism, I ma v use a plunger p(indicated diagranimatically iniFi l and 5) which `will reciprocate in agulde 1'2 on the carrier frame, and be operated by zr'rocker arin s2(Fig-5) for example, connected and deriving its motion from somesuitable part of the machine; and vill o eratpi at the ro er timeafrainst a epen ing4 nger' IFiu- 5) on thte arm c,'l pushing that `iigirand consequently the arm k back far enough to lift the upper jaw therequi `l distance before the ejector acts. I have not deemed series ofholes y' in prior to ejectiiig the cast slug.

il i5 vfro movement of the mold.

` justed position of ing position w ermee it necessaryT to represent theactuating mechanism here. Any suitable mechanism of the kind can beemployed, as for example that. shown in my Patent llo. 834,971 orNovember 6, 1905.

lt remains `to describe the mechanism for moving the lower jewlengthwise for the purpose of changing the length of thc slot and forautomatically opening` and closing the slot in this direction during theto and lily mold in this respect, is characterized by the combinationwith the member which is longitudinally movable in relation to theothers for the purpose of changing the length of the slot, ot stops i'orautomatically and positively opening and closing the mold to one lengthor another during its movement to a nd irc. This feature is not herebroadly claimed, inasmuch as it is the subject (among others) of myapplication ior a vpatent for improvement inline casting i. achinesSerial No, 432,605, filed May 13, 1.988. ln said last.- namedapplication one o' the stops is a fixed stop which automatically opensthe ,mold al: ways to maximum length, and the other is an independentlyadjustable stop which art-y tomatically closes" the mold to one lengthor another as desired.

ln my present application, the twostops are placed at e dist-ance apartslightly less than the length of traverse of the mold, and are soconnected asto be adjustable bodily and together, the distance betweenthem being invariable, so that the automatic opening movement of themold will always be the same in extentwhatever may be the zid-v thestops. ln the drawing the two stops are shown at r, rf; are attached toopposite ends ot ti e slotted. bar s Jfrom the face of which theyproject in the pathxof a vertical bar t attached, et. its ends .to thecarrier G and extending down in front ot the mold. yThe bar .9, which ontop of front plate 8, is arranged horizontally on the front face of thelower jaw i,

ejector or its -passing between it and the vertical barI t.

w il by set and is adjustably secured to the ja slot in the screw swhich passes through the bar into: the lower jaw. Thebar s can beadjusted back and forth vto change the relation 'of-the stops 7', r tothe intermediate vertical bar and can then, by tiglitoniuig; the setscrew, be held firmly in its adjuster position. A, scale can be formedon the bar s, a. shown, to facilitate adjustment as usua in devices ofthis character.

The closingstop is r; fr is the opening stop. ln Fig. l the mold isshown'in cast-- ith its members in position to forni :t slot of maximumdimensions in both directions. ln movingv from casting` toejectingposition, stop 7, just before the mold reaches'lejectinkposition, brings up against bar t, thushol ing bach the lower jew while'they.

i l l l the rest of the mold moves forward. and consequontly increasingthe distance between the side. pieces 3, 5, or in other words the lengthot' the slot. Un the-return movement of the mold the reverse actiontakes place; the closing stop i' brings up against the bar 1, and holdsthe lower jaw motionless, while the remainder oi" the mold moves 'back`to casting position. To decrease the lengthof the slot, the bnr s,while the mold is in ejecting` position, is adjusted to the left, so asto bring' the stop fr' sooner into contact with -the bar t' during thereturn movement of the mold, es will be understood without furtherexplanafrigm. I
